My invention relates to suction nozzles for use in connection with a vacuum cleaner, and more particularly to a two-part nozzle which is capable of providingat least three diil'erent types of nozzle openings.

In accordance with my invention, the device includes a nozzle body having a comparatively (Granted under the provisions of sec. 14, act of March 2, 1927; 357 0. G. 5)

small elongated suction opening. Such a nozzle side of the base portion is formed as a nozzle of one type, whereas the other side is formed as a nozzle of a different type. either one of which may be placed in an operative position, depending upon which side of the base portion is secured to the ilrst nozzle body.

Further objects andadvantages of my invention will be apparent from the following description considered in connection with the accompanyins drawing whichforms a part of this speciilcation and of which:

Fig. 1 is a side view, partially in cross-section of a preferred embodiment of my invention;

Fig. 2 is a top view of a portion of the device shown in Fig. 1;

Fig. 3 is a cross-sectional view, on an enlarged scale, taken on the line 3-3 of Fig. l, but with one of the parts in reversed position; and

Fig. 4 is a cross-sectional view, on an enlarged scale, taken on the line 4-4 of Fig. 2.

Referring to the-drawing, reference character Il designates generally a rst nozzle structure.

-This structure includes a substantially cylindrical portion II which is adapted to receive a conduit leading to a source of suction. The interior of portion II connects with an' elongated suction for cleaning purposes where it is desired to concentrate the iiow of air over a comparatively small area. This makes it possible to remove dirt, such as threads, dog hairs, etc., which .ad--

here tenaciously to the"surface being cleaned. Such a nomle is also advantageous for cleaning be readily manipulated. "However, such a nozzle is not well suited for removing ordinary dirt from a large surface, such as iloor or floor covering; due to the fact that' it covers such a small area that it would require an imduly long time to complete the cleaning.

Referen character I4 designates generally a second nozzle structure which is adapted to be used in connection with the nozzle III. The nozzle I4 is advantageously made of a sheet metal stamping and includes a substantial ila't base portion l5 which is formed with an .ope g I6 extending therethrough. Opening I6 is f substantially the same size and'shape as is suction opening I2 in nozzle I0. Extending from the b ase portion I5 adjacent to the edges thereof is a lip or rim I'I. As shown, particularly in Figs. 3 and 4, the base portion consists of two thicknesses of sheet metal, one of which is stamped so as to make a hollow rim I'I. This rim is formed with an opening I8 toward the opposite side of the base portion from which the rim extends.

Brush bristles I9 are secured within the ,hol-

low portion of the rim I'I and extend through theopening I8 and beyond the aforesaid opposite side of the base portion. Thus, one side of the base portion is provided with a. so1id rim or lip surrounding the opening I6. whereas the other lside of the base portion is provided with a row of brush bristles surrounding this opening.

In order to secure the nozzle I4 to the nozzle I0, the base portion of the former is provided with a stationary memberV 20 and a, displaceable member 2l, each of which members is provided with a pair of recesses 22 which are adapted to engage the bead I3 formed on the nozzle I0. In order to secure the members 20 and 2l to -the base portion, the xtwo sheets of metal forming the xfaarmme, beeause, due to its small size-1t may 55 latter are stamped or otherwise shaped'to-provide cylindrical recesses 23 and 24. Recess 23.

receives a cylindrical end 25 of member 2l and movement of the member 20 within the recess is prevented by means of an indentation 28 in one of the metal sheets, engaging a recess formed inthe cylindrical end 25. The member 2I is formed with a cylindrical end 21 which is slidably receivedwithin the recess 24. Member 21, as is clearly shown in Fig. 4, is provided with a transverse pin 22 which is slidable within the transverse grooves 29 formed in the sheet metal, thus v preventing rotation of the member 2|. A spring 3l is received in recess 24 and serves to urge the member 2l to the right, as viewed in Fig. 1. Movement in this direction'is limited by engagement of the pin 28 with the ends of the grooves 29.

by the lip I'I. This inlet is considerably longer' than the inlet I6 in the nozzle I0, and consequently is able to clean a large area in a comparatively short time. Such a nozzle is suitable for cleaning rugs, carpets, or other floor covering. t

When it is desired to use a nozzle provided with brush bristles, for instance for cleaning hardwood iioors or other hard surfaces, the nozzle member I4 may be removed from the nozzle I0, turned over and secured to the nozzle III with the bristles I9 extending downwardly, as is shown in Figs. 1 and 4. With the parts in this position there is thus provided a large brush nozzle which will cover a large area in a short time.

In order to connect Ythe nozzles together, one

y of the recesses 22 in the. member 20 is placed in engagement with the bead I3 on the nozzle III, while the member 2| is placed just below the bead. If the two nozzles are then pivoted towards each other about the point of contact between the bead I3 and the member 20, the beveled end of member 2l will force this member to the left, as viewed in Fig. 1, against the action of spring 30 until the bead I3 has entered the recess 22. The spring 30 then holds the member 2| in engagement with the bead and the two nozzles are thus secured together. In order to separate them, the nozzles are pivoted away from each other about the point of contact betweenthe member 20 and the bead I3, the beveled portion of the member 2| again serving to cause .this

member to be displaced to the left, as viewed in V Fig. 1, thus permitting the bead I3 to come out of engagementwiththe recess 22. Hence, there is provideda quick and easy means for securing the two nozzle parts together, and for separating them. During use a downwardly directed force is normally applied to the nozzle III, which forces it against the base portion of the nozzle I and thus there is no tendency for the two nozzles to become separated.

While I have described one more or less specific embodiment of my invention, it is to be understood that this has been done for purposes of illustration only, and that the scope of my invention is not to be limited thereby, but is to be determined by the appended' claims.
